1. Air Force Scientists Collect 99 Percent of Wave Energy - A growing industry, wave power technology is increasingly becoming more efficient. Scientists at the U.S. Air Force Academy base in Colorado Springs have demonstrated that submerged wave energy converters can harness up to 99 percent of the kinetic energy inherent in an ocean wave.
Last year, U.S. President Obama proclaimed that clean coal is the bridge his country needed to gap the time it would take renewable energy to supply enough power to meet U.S. energy demand.
A new study from Harvard University has found that when the entire life-cycle of coal is considered -- extraction, transport, processing, and combustion -- it poses significant public health and environment hazards. Cumulatively, the study estimates these hazards cost the American people roughly US$300 to US$500 billion dollars annually.
